TEST
1
Start the engine.
With the DRBIII , read the MAP Sensor voltage.
Is the voltage below .078 of a volt?
Yes → Go To 2
→ Refer to the INTERMITTENT CONDITION symptom in the
No
2
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the (K6) 5 Volt Supply circuit in the MAP Sensor harness
connector.
Is the voltage between 4.75 to 5.2 volts?
Yes → Go To 3
→ Go To 7
No
